ASTM A283 Carbon steel sheet

Chitsulo cha ASTM A283 chimakhala ndi mbale yotsika komanso yapakatikati yolimba ya carbon steel yamtundu wamapangidwe. Ili ndi mitundu inayi yofanana, iliyonse imayimiridwa ngati chinthu chosiyana. Gawo lazinthu zomwe zili pansipa zikuwonetsa milingo yomwe ili ndi mitundu yonse.

Kufotokozera uku kumakhudza magawo anayi a mbale zachitsulo za carbon structural quality kuti zigwiritsidwe ntchito. Zitsanzo zachitsulo ziyenera kusungunuka ndi ng'anjo yamagetsi, ng'anjo yamagetsi yotseguka, mpweya woyambira, kapena ng'anjo yamagetsi. Kutentha ndi kusanthula kwazinthu ziyenera kuchitidwa momwe zida zachitsulo zimayenderana ndi zinthu zofunika za carbon, manganese, phosphorous, sulfure, silicon, ndi mkuwa. Zitsanzo zachitsulo zidzayesedwanso kuti zigwirizane ndi zofunikira za kulimba kwamphamvu, zokolola, ndi kutalika.
